My guess is that you are not using the correct headers.
I saved your code to a file named xtest.c and compiled it like this
(egcs-1.02, NT4 SP3):

gcc -I/usr/X11R6.3/include -o xtest xtest.c /usr/X11R6.3/lib/libX11.a

and I get no SIGSEGV. However, if I compile it as:

gcc  -o xtest xtest.c /usr/X11R6.3/lib/libX11.a

it builds allright but gives the same SIGSEGV you got. When you
omit the  -I/usr/X11R6.3/include you are likely using the
X headers part of tcl/tk80, therefore the pointer incompatibility.
